SEWING-MACHINE TABLE.

SPECIFICATION forming part of Letters Patent No. 552,507, dated January7, 1896,.

Applicants nea April 41o, 1893.

To all whom, it may concern:

Be it known that I, JAMEs BOLTON, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Sewing Machine Tables,of which the following is a specification, reference being had thereinto the accompanying drawings.

My invention relates to sewing-machine tables or stands, and moreparticularly to that class thereof which are so constructed as to permitthe sewing-machine, when not in use, to be dropped down below thesurfaceof the table, so that by folding down'the leaf which forms anextension of the table, onto the surface of the latter, the opening inthe table proper is covered,and thus the table is adapted for use as anordinary table, this class of stands being known to the trade asdropcabinets.

The object of my invention is to provide a brace for the class ofsewing-machine stands or tables referred to, which brace is of suchconstruction that the driving-wl1eel of the machine may be mountedthereon and be out of the way of the operator, the brace being so madethat it may be quickly and cheaply secured to the legs or side frames ofthe table, and the screws by which the bottom portions of the brace aresecured to the said legs or side frames serving also as centerscrew-bear ings for the treadle. The bearing for the driving-wheel is ofsuch construction that it may be adjusted to compensate for wear.

In the accompanying drawings, Figure l is a front view of asewingmachine stand embodying my invention, the legs or side frames ofthe stand and the table portion thereof being denoted simply by dottedlines. Fig. 2 is a detail sectional view of the bearing for thedriving-wheel. Fig. 3 is a detail sectional view of one of the bearingsfor the treadle, and Fig. 4C is a partial cross-section showing thereceptacle for the machine when the same is dropped beneath the table.

A A denote the legs or side frames of a sewing-machine stand or table,these being usually of cast-iron.

B is the table portion of the stand, and C denotes a receptacle beneaththe table into serai No. 469,779. (No model.)

which the machine may be dropped when not in use.

The sewing-machine (denoted by dotted lines in Fig. 4) is mounted upon ahinged section h of the table B, said hinged section b being supportedin front by a second smaller hinged section b, which, when the section his lifted slightly, may be turned upward to permit the said section Z2with the sewingmachine mounted thereon to fall down below the table Binto the receptacle C in the direc tion denoted by the arrow in Fig. 4.The brace which connects the legs or side frames A, and which serves tostiifen and steady the table, comprises the curved outer vertical partsor bars d and the horizontal bars d d2, the latter having the extensiond?.

The outer ends of the upper horizontal bar d are screwed or bolted tothe side frames A in any suitable manner, and the lower ends of the barsd are secured to the said legs or side frames by means of screws a,tapped through the said legs or side frames and passing loosely throughthe lower ends ofthe bars d of the brace, the said screws being roundedor pointed at their inner ends to serve as center or bearing screws forthe treadle E, which is mounted thereon, as more clearly shown in Fig.3, setnuts a being provided to hold the screws in any desired positionof adjustment to firmly lock the lower ends of the brace to the legs orside frames of the table.

The upper horizontal arm d serves as a support for the box or receptacleC, which incloses the machine when the latter is dropped below thetable. The part d3 of the lower horizontal bar d extends outside of oneof the vertical bars d and is preferably formed conical at its outerend, as shown in Fig. 2, so that it may fit in a oorrespondingly-shapedrecess or countersink in the inner side of the hub of the driving-wheelF, the outer side of said hub being also countersunk for the receptionof the conical head on the screw f, which is tapped into the extensionor bar d3, and which screw serves as a bearing for the said drivingwheel. The screw f may be turned, when desired, to compensate for wearat the hub of the driving-wheel, and is secured in. any desired positionof adjustment by the set-screw f.

By arranging the driving-wheel, as shown,

IOO

outside of one of the curved Vertical bars of the brace,the latter, itwill be observed, serves as a guard to prevent the dress of the operatorfrom coming in contact with the drivin g-wheel or with the pitman g,which connects said wheel to the treadle E.

It will thus be seen that by the simple form of brace herein shown anddescribed I am enabled to provide an eiicient compensating bearing forthe driving-wheel, and a bearing for the treadle as well as adress-guard, while the brace itself, although simple in construction,serves as a support for the receptacle C and strongly braces the wholetable and renders it firm and efficient.

Having thus described my invention7 I claim and desire to secure byLetters Patent-- l. The combination with the table and legs or sideframes of a sewing machine stand provided with a receptacle into whichthe sewing machine may be dropped when not in use, of a brace connectingsaid legs or side frames and to the outer part of one side of which thedriving wheel is j ournaled, said brace having an upper cross-barserving as a support for said receptacle and being provided at its lowerend with screws which serve to secure the same to said legs orside-frames of the stand and which also serve as bearing screws for thetreadle.

2. The combination with the legs or side frames of a sewing machinestand, of atablc attached to the tops of said legs or side frames, areceptacle beneath said table into which the sewing machine may bedropped when not in use, and a brace connecting said legs or side framesand to the upper part of one side of which the driving wheel isjournaled, said brace having an upper cross bar serving as a support forsaid receptacle, substantially as set forth.

In testimony whereof l affix my signature in presence of two witnesses.
